F ST. PAUL, MINNESOTA WINDOW Application led lay 23,

My invention relates to Windows for buildings, the primary object of which is to pro-' vide a new means of supporting the window panes or glass in such a manner as to permit 6 the glass to slide freely so that the Window panes may be readily opened and to overcome the necessity of using a sash frame about the Window pane. Therefore my window is primarily of a type wherein no sash frame is 10 required about the window pane or glass.

A feature of my invention resides in a frame having means for anchoring the edges of the frame into the building structure, either into a brick wall, brick and tile, or a wood structure, or any other form of building wall that may be employed, so that a virtually weathertight joint is made with the wall and the sides of the frame which support the window panes.

In this manner I provide a means of overcoming a very objectionable feature with the ordinary wooden window frame which are inclined to shrink and permit a draft of air about the frames in the ordinary buildings where these wooden frames are used.

It is also a feature of my invention to provide grooves for the panes of glass of my window so that the windows may be raised or lowered in the grooves and thus I provide a felt means of contacting with the sides of the windows and form a weather-tight joint in the frame between the window pane and the frame.

vA further object of my invention resides in a Ventilating means which is provided between the window panes.

structed with the usual upper and lower window panes and between these window panes I provide the ventilator which also forms the meeting rail between the lower edge of the upper pane and the top edge of the lower pane. This ventilator feature of my window is very important as it provides a means of ventilating a room wherein my window is used without opening either of the window panes and owing to the nature of the ventilator and meeting rail member which is pivotally supported between the window panes and transversely across the frame between the ends thereof, it is possible to tilt the ventilator in such a manner as to permit a ventilation int-o My window is con-` 1928. serial No.' 2805034.

the room without the disadvantage of having the rain beat in through the open window as is true of the ordinary types of windows used heretofore when they are opened either at the top or bottom.

It is also a-feature of my invention to provide a meeting rail which can be readily removed and to provide a window structure wherein the Window panes may be readily removed in a very simple manner. My window 00 and frame structure is sim le in construction and economical to manutizicture, also having the advantage over the framed type of windows with the sliding sash which are apt to give considerable trouble at times when the window sashes stick in the frame.

These objects together with other details and features will be more clearly and speoiiically dened hereinafter in the specification and claims. 7

My window is formed with an upper pane A and a lower pane B of glass. These panes A and B are positioned to operate in the frame C in virtually parallel relation and 1L s aced apart so that they may slide up and down in the frame to open or close the win- The frame C of m vwindow is provided with a side plate 10 w ich is channel shaped and formed with the flanges 11 and 12 which are anchored in the Wall structure 13 where the wall structure is made of wood, as illustrated inFigure 3, and in the wall structure 14, where masonry is used. The fiange portions 11 and 12 are formed with opemngs 15 so that where the side plates 10 are anchored into a masonry or brick wall the lianges 11 and 12 are held firmly in the wall structure.

The side plate 10 is formed with a longitudinally extending bead 16 which is positioned extending from the side 12 and is formed by bending the side plate 10, as illustrated in Figures 3 and 4. The bead member 16 has an inwardly projecting portion 17 which is adapted to project towards the upper window pane A. A strip of wood or other suitable material 18 is placed in the bead being held in position by the inwardly projecting lip 17 and forms a bearing for the ed of the glass of the upper window pane so that the glass will not bear directly against the lip 17. The side plates 10 are preferably formed of metal or other suitable material and while the strip 18 which is nonmetallic is not entirely essential, I prefer to include it for engaging the edge of the window pane. This strip 18 may..

be of felt or other similar material to form one side of the groove in' which the edge of the lass A is adapted to slide.

e window pane A is adapted to be held by the sash balancers D which are spring operated and which are placed in the upper part of the frame C of my window. The spring balancers D are provided with lifting straps 20 which extend along the plates 10, as illustrated in Figures 3, 5, and 6. The lower or free ends of the straps 2O are connected by means of links 21 to the glass A, as illustrated in Figure 5. Thus the balancers D operate to lift the window pane A in the operation of the same. The window pane B which forms the lowerl glass of my window is positioned on the inner side of the frame C and is adapted to be balanced by the spring balancers E which are similar to balancers D and which are provided with lifting straps 22 which connect by means of the links 23 to the window pane B, as illustrated in Figures 2 and 5. The lifting straps 22 also extend along in close proximity to the plates 10 at the side of my window.

I provide the molding strips 23 for the inside of the edges of my window pane B so as to hold the window pane virtually parallel to the window pane A. Between the window panes A and B and forminfr a part of the frame of my window I provide side plates F which have flange portions 26 and vwith the sill 32 of the frame, While t 27 rojecting towards the window panes A andpB, respectively, as illustrated in Figure 8. In these flange portions I provide felt strips 28 which are ada ted to engage the window panes A and B) soas to form a weather-tlght joint. s

The edges of the window panes A and B can be adapted to slide in felt strips on either side if it is desired and. thus provide a weather-tight joint which prevents the wind or a draft of air passing the ed es of the window frame into the room. ith my window it is not necessary to use weatherstripping as is true with the ordinary wooden sliding sash frames, and yet I can provide a weather-tight joint about the window panes A and B.

The u er window pane A is provided with a t 1n metal strip of a channel shape 30 secured to the lower edge of the same as` illustrated in Figure 5 and which is rovided with a water drip 31 extending a ong the outer lower edge of the same. The ower window pane B is also provided with a similar weather-stripping 30 having a Water drip 31 formed longitudinally along the same. These strips protect the lower edges yof the window panes A and B and when the lower window pane B is in closed position the strip 30 forms a weather-tight joint e uppe: strip 30 on the upper pane A is adapted to contact with the meetin rail 33 in a manner to form a weather joint therewith, whr n the meetin rail 33 is in closed position as illustrated 1n Figure 5.

The meeting rail 33 is by the bolts 34 in the si e plates F of the frame C. These bolts may be withdrawn from the side plates F by removing the cap 35 and engaging the bolts 34 to withdraw the same from the side plates F. This permits the Ventilating meeting rail 33 to be readily removed or lnserted in operating position in my Window.

The ventilator or meeting rail 33 is formed with a groove 36 which is adapted to engage the upper edge 37 of the window pane B, when the meeting rail ventilator 33 is in closed position, as illustrated in Figure 5.

I provide a locking bolt means G for the meeting rail and ventilator 33 which is operable by the thumb bolt 38 to operate the bolt rods 38 into and out of engagement with the side plates F.

This bolt Gr is provided with a gear member 40 on the inner end of the same which engages in the rack gears 41 formed in the loops on the inner ends of the rods 39. Thus when the bolt G is rotated the rods 39 are caused to engage or disengage the side plates F. When the catch G is operated to disengage the bolts 39 from the side plates F the ventilator meeting rail 33 may be tilted on its axisor supporting bolts 34 as illus= ivotally attached l trated iu dotted outline in Figure 5 and also in Figure 2. When the meeting rail is turned in this manner the window panes A and B can be opevted by engaging t-he buttons 42. Thus the window anes A and B can be slid up and down iu t 1e respective grooves formed in the sides of the frame C in much the same order as istrue of the ordinary window excepting that no window sash is employed for the glass panes A and B. This simplifies the construction of my window and overcomes the sticking of the sash frames in the window frame and also obviates the neccssity of any frame for the glass of any nature whatsoever,- thereby providing an economical construction to the window and permitting the window panes A and B to slide very freely when desired.

A feature of primary importance in my window is that the side plates such as 10 form a sealing means with the wall so that the wind or draft cannot enter the building about the frame C. This is accomplished by anchoring the flanges 11 and 12 into the wall ofthe buiding. I further weather proof my window by the side plates F which carry the felt strips 28. These bear against the surface of the edge of the window panes A and B so as to prevent any draft of air over the edges of the window pane into the building. The window panes A and B are similarly sealed at the top and bottom in the frame C and the meet-ing rail 33 is formed with suitable felt means in the `groove 36 and the felt strip 44: contacting with the lower edge ofthe window pane A, so that a substantially weather-tight window is provided which is a very desirable feature. The construction of my window overcomes the necessity of any weather stripping such as is ordinarily used with wood sash for windows.

The window panes A and B of my window may be easily replaced or taken out when it is desired and the fact that the meeting rail 33 is also easily removable provides a construction of a desirable nature.

My window is particularly adapted to plate glass window panes such as A and B, however, other glass of a desired thickness may be used equally well. The plate glass may be used in my window in so far as I know at a cost not greater than the ordinary window with only double strength glass owing to the fact that my window is more economical to manufacture and thus a better window can be provided at virtually the same price as the ordinary old style windows.

A feature of primary importance of my invention resides in the simple and effective operation of the ventilator meeting rail. This meeting rail ventilator 33 permits a room to be ventilated by opening the meeting rail ventilator 33 either very slightly or wide open, as illustrated in dotted position in Figure 5. If the ventilator meeting rail 33 is opened just slightly it. tilts with its outer edge downward in such a manner that rain will no come into the window through the ventilator even though the same is opened quite wide and this is a very important feature, because it permits a room to be ventilateltgl without opening the window panes A or In accordance with the patent statutes I have described the principles of operation of my window and while I have illustrated a particular formation and construction of the parts I desire to have it understood that the same is only illustrative of a means of carrying out the invention and, that variations may be made within the scope of the following claims without departing from the purpose and intent of the invention.
